Video of Nicholas Zakas from his Fluent Conference 2012 Presentation
Maintainable JavaScript tackles the difficult problem of writing code as part of a large team. When you’re writing code that only you will change, there aren’t any issues. As soon as you’re writing code that someone else is going to also be changing, you need to think harder about the decisions you make. Will another developer be able to understand what you did? Did you organize your code in such a way that it’s easy to adapt and extend? Long after you’re gone, will others be able to continue using the same code, or will it need to be rewritten because no one understands it? This session shows the best practices used by teams to ensure their JavaScript is as maintainable as possible.

Bitch.
He looks like Steve Jobs, junger JavaScript genious!
lol "Knuth is my homeboy"
Great video. Very helpful. Thanks 🙂
Just because JavaScript is classless, doesn't mean you have to be ))))
did he said IE when he coughed? :p one of the few videos I re-watch frequently. This man is awesome.
The XMLHttpRequest name feels wrong no matter how you write it.
Xml? Who capitalizes Xml? Ok, all caps then, like in the wild
But how about the Http part then? If we put it all caps the reader will lookup for the new XMLHTTP protocol. We need to separate it somehow. Underscore? Well yes, but we use underscore for separating words in variable names.
There is absolutely no way to win this. Only by completely changing the object name. But how could you name the object of an XML HTTP request? ARGH!
Interesting enough to stick to till the end,
resourceful enough to take away some great tips.
Great great talk, witty funny. Thx.
Thats one thing that makes Java and class based languages better than Javascript. If someone overrides a method in Javascript it can take days to figure out the bug. However in Java its only a matter of seconds to find incompatible overrides due to compile time checking.
+Tomás Martínez check this out xD 28:10 me recordó a ti xD
don't be afraid of long names and name things logicaly: AbstractSingletonProxyFactoryBean
I too like Nicholas Zakas, both his writing and speaking. No pun intended, but I find his speech very fluent, and the combination with his profound knowledge makes it awesome.
Awesome talk. Tools are not as up-to-date anymore, but generally awesome.
Use class name to change the style;
Wow! "Just because JavaScript is classless you don't become". 🙂
I like Nicolas Zakas’ talks a lot, because they are densely informational and I always take a lot out of them. What I don’t like about them is N. Zakas’ often embarassing attempts at humor (which – admittedly – mostly suffer from the moody reactions of the respective ,crowd’ he’s speaking to).
In this one however, he seems much more relaxed and does not try to enforce laughs, which made the whole talk not only informative, but also very entertaining and even funny.
Yes i mean it. we must kill the bad fat and belly first to get the 6 pack.
Listen to this I saw an interview with body building champion where he talks about 7 odd foods he eats to keep his abs hard.

There's a HD version in the description, no?

I have no idea why they uploaded it twice but this one has 720p
Try to maintain the size of your Javascript to zero bytes. It's the best choice unless you want popups on your site, you don't need and/or want it.

So simple. Thanks dude!
Add a CSS class instead – that's what they're for, updated your jsFiddle: jsfiddle.net/5Ba2u/3/
I am new to Javascript coding and thought this was a great video!
I have a question though.
At 30:00 it says to keep css style out of Javascript. How would one manipulate the css style of an html element then?
Example code:
jsfiddle.net/5Ba2u/
How would the above be done for better coding practice?
Thanks in advanced.
I assume you're referring to the fact that Pi is all caps? All of the Math constants are capitalized, following the general practice of capitalizing constants (the slide following camel casing).
My bet is that it was a joke …
I'd just like to state for the record that "Id" is not an acronym, its an abbreviation. It means "Identification" or "Identifier", not like "I-Dentifier". So capitalizing both letters would be incorrect.
24:00, what about Math.PI ?
getElementById & innerHTML is not JavaScript but DOM API !

I once had a 45 minute argument about whether or not JSLINT errors should break our jenkins build. Though the style itself doesn't effect the program, it was a good way to enforce our style guide. Any thoughts?
Very Userful Talk.
very useful stuffs. thanks, nicholas.
Harshed word I heard was crap and I don't view that as an expletive. I do however view IE as an expletive if it refers to any version before 10.
LOL, 9:25 "Debuggable… which is not a real word… btw… According to M$ word anyway." I can't tell if he was telling a joke there or not.
Wow, the only expletive I heard was "Internet Explorer"
The slides: slideshare. net/nzakas/maintainable-javascript-2012
Great talk, could have done without all the expletives, had ask my four year old leave the room.
This is a great video. JavaScript doesn't allow you to really split your programming patterns but this video gives you simple tips on how to understand and maintain JavaScript code better.
